The cornea: the window of the eye The cornea: the window of the eye Regular astigmatism Very common type of refractive error in normal eyes One meridian of the cornea is more curved than the other: as a result the curvature of the cornea looks like a rugby ball rather than a round foot ball This error can be easily corrected with Foot ball (spherical shape) spec(teRaguggcbshlyaebpaeslld)and soft (toric) lenses Figure from https://www.slideshare.net/helleravinas/astigmatism-56625998 Irregular astigmatism Occurs only in eyes with corneal disease (keratoconus, scars,...)
